There are important regulations that have been created to keep our waters clean and our communities safe. This page contains information on recent updates and changes that affect Landscaping Professionals working in both residential and commercial areas.

The Department of Pesticide Regulation (DPR) has implemented new restrictions that will strictly limit the amount of pesticides applied outdoors, especially to concrete and other hard surfaces. The policy applies to 17 different pyrethoid insecticides applied by commercial businesses. It is now prohibited to apply these pesticides during rain or in standing water conditions as well as over drains and in natural drainage areas.

For a more detailed explanation check out this presentation created by DPR: http://www.cdpr.ca.gov/docs/emon/surfwtr/presentations/pepple_swregs_upc_2_1011.pdf

Pittsburg Municipal Code (PMC) - Irrigation Practices

Excessive irrigation can contribute to pesticides flowing into the storm drains, creek, and the bay. On December 20, 2010 the City of Pittsburg revised the City’s previously adopted water-efficient landscape ordinance in recognition of the mandate in Assembly Bill 1881(Laird) and in accordance with the State Department of Water Resources’ model water efficient landscape ordinance intended to ensure the conservation of water in irrigated landscaped areas. The revised ordinance outlines the current standards and requirements for projects creating or rehabilitating landscaping. See PMC Section 18.84.31 for project applicability.

Runoff due to excessive irrigation is considered to be a non-stormwater illicit discharge and is a violation in accordance with PMC 13.28.060, Prohibited Discharges. Any persons found to be violation will be issued notices of correction and may be subject to fines. Best management practices for landscape maintenance and efficient irrigation practices are to be used. Excessive irrigation runoff can be mitigated by reducing the irrigation run time and/or adjustments to spray heads to prevent overspray.

Did you know?
The most common violation is EXCESSIVE IRRIGATION. It can lead to the runoff of trash and dangerous chemicals into our Delta, creeks and bay.  Help conserve our precious resource and help keep our waters clean, healthy, and safe for our communities by only irrigating a responsible amount.
